Title: Process to provide with decorative designs elastic thermoplastic sheets
IPC: B44C1/17
Filed: 1945-05-15
Abstract: 592,548. Transferring designs ; transfers ; embossing. RADO, L. May 15, 1945, Nos. 12159/45, 35209/45, 35210/45 and 6067/46. [Class 100 (ii)] In the production of designs, which may be printed or embossed or both, on pliable, elastic sheets made from a thermoplastic substance, such as a vinyl resin, in particular polyvinyl chloride, the sheet is laid between two nohthermoplastic media of which one at least is pliable and carries a design, heat and pressure are applied whereby the. sheet becomes plastic and the design is transferred thereto or an impression of the design is embossed or both, the sheet is allowed to cool while between the two media whereby the sheet regains its elasticity, and at least the design-carrier is removed. The design may be printed in a thermoplastic ink on a carrier having a fibrous-free surface, e.g., aluminium foil glued to a paper or fabric backing, or paper impregnated with gum, glue or oil, or hydrated. At least one of the non- thermoplastic media may consist of unimpregnated paper, the surface fibres of which become permanently embedded in the vinyl sheet, the resulting misty appearance being corrected by treating the free ends of the fibres with oily substances or transparent lacquers to make the fibres transparent. A permanent backing may be provided for the vinyl sheet by applying a woven fabric to the sheet before applying the transfer ; alternatively, one of the media may form such a backing, or a fabric sheet may be placed between two vinyl sheets, the three sheets being united before or during transfer. The raised part of an embossed design may be coloured by spraying ink on to an embossed design carrier and removing surface ink. Metal foil of thickness 0.025-0.4 millimetres backed with paper weighing 40-60 grams per square millimetre, or thin paper weighing 25-30 grams per square millimetre are examples of design carriers. Temperatures of 100-120‹ Centigrade for ordinary transferring and 130-150‹ Centigrade to obtain a highly glazed surface are specified. Films made by extrusion may be immediately laid between the cover sheets and heat and pressure applied. Fig. 1 shows apparatus for carrying out the process wherein a web 1 of the vinyl product sandwiched between slightly wider carrier webs 2, 3 passes around a heated cylinder 6 under pressure from rollers 7-9, and then through a cooler 10, the webs being rewound separately on rollers 13-15. Other forms of apparatus comprise (a) a pack of vinyl sheets, Fig. 2 (not shown), interleaved with design carriers and pressed between hot plates, (b) a vinyl web and a carrier web wound together on a mandrel which is placed in an oven and rotated, Figs.' 4 and 5 (not shown), and (c) vinyl and carrier webs unwound from rollers and passed between rollers to a hot press followed by artificial cooling and rewinding, Fig. 6 (not shown). Specification 562,573 is referred to.

Title: Improvements in or relating to steam traps
IPC: F16T1/24
Filed: 1922-05-01
Abstract: 200,950. Monahan, T. W., and Wilson, T. C. May 1, 1922. Steam traps.-In steam traps having a float or bucket and tumbler mechanism for automatically operating two valves, the float and a rocker arm are mounted on a shaft, the arm operating a loosely mounted weight member which in turn moves a twoarmed leaver on a second shaft from which a disc valve is controlled, whereby the pressure on the casing is altered for the filling and draining functions of the trap. The float container 1. Fig. 1, has an inlet 7 and outlet 6 each having a non-return valve fitting. The container also has a gauge glass 10, a pipe 16 open to the atmosphere, a pipe 15 connected to the condenser, a pressure gauge 14, and a pressure equalizing pipe 5<1>. A float 20, Fig. 3, on a shaft 17 moves a rocker arm 19 which in turn moves a weight 21 up to its vertical position after which it continues to move under gravity. Stops 22, 23 limit the movement of the weight. Arms 25, 26 on a shaft 27 are moved by contact with the weight and thus operate a valve disc 28 on the shaft 27. This disc controls ports in a valve body whereby in one position the container is coupled to the pipe 15 for keeping the pressure below that of the condenser and allowing the container to fill or in the other position is coupled to the pipe 16 for allowing the container to drain. The valve disc is kept on its seat bv a spring 38, the compression of which can be adjusted. The valve and shafting are carried by a casting 51 bolted to the casing 1. In a modification, a bucket is used in place of a float, and the valve disc has rollers for reducing friction.

Abstract: 559,755. Rowlocks ; oars. CROSS, L. H., and CRAWFORD, W. Aug. 31, 1942, Nos. 12233 and 13653. [Class 114] The ends of the horns of the stirrup 1 of a swivelling rowlock of a rowing boat are provided with holes 2, 3 for the detachable engagement of an oar-retaining member spanning the horns, and engaged by a supplementary abutment 21 on the oar 4. As shown in Figs. 1 and 5, a bolt 6 or other rigid retaining member may have one or a pair of lugs 7 or flats to pass through a slot 8 radiating from either or both holes 2, 3. The lugs 7 are rotated into a retaining position by the gravitational influence of a radial finger 9 on the head 10 of the bolt. A keeper cord 12 for the bolt is secured to an eye 11 on the finger 9 and to an eye 13 in the shank 14, and, by binding the cord at 15, the extension 12a of the cord may be secured to the oar. As shown in Fig. 3, the cord 12 or a wire, chain, or other flexible retaining member, may replace the bolt 6, and its remote end may be fastened to a cleat 18 on the rowlock or to an anohorage inside the boat. The holes 2, 3 may be formed by rolling over the upper ends of the horns of the stirrup, and, on its way to the eye 13, the cord may be passed through an eye on a ring fitted in a circumferential groove in the boss 24 of the stirrup. The Provisional Specifications describe one or more cross-bars for a flexible retaining member, and modified arrangements for securing the keeper cord.

Title: Egg Product
IPC: A23L15/10
Filed: 1968-03-13
Abstract: 1,157,065. Egg product. TERIMPEX ALLAT-ES TERMENYFORGALMI KILKERESKEDELMI VALLALAT. 13 March, 1968, No. 12261/68. Heading A2B. An egg product in the form of an elongated body of coagulated egg yolk surrounded by coagulated egg white is obtained by moulding and coagulating egg white to form a hollow cylinder, filling this cylinder with egg yolk, and coagulating the yolk. For example, the egg white may be introduced into the annular space between two concentric tubes, preferably of stainless steel, which are closed at their lower ends, coagulated by placing in boiling water, removing the inner tube, introducing the yolk, and coagulating by further boiling. The egg may be fresh or reconstituted. The product may be employed in meat products. For example a canned luncheon meat having a central core of egg is prepared by having a stainless steel cylinder of slightly larger diameter than the egg stick inserted in the empty can which is then filled with the meat, the cylinder withdrawn, the egg stick inserted, and the can thereafter closed and processed conventionally.

Title: Method and apparatus for operating a rollstand or a roll train formed by rollstands
IPC: B21B39/14
Filed: 1972-03-16
Abstract: 1381664 Rolling mills SIEMAG SIEGENER MASCHINENBAU GmbH 16 March 1972 [30 March 1971] 12298/72 Heading B3M The stiffness of a roll stand is held at a predetermined value by the roll gap adjusting mechanism of the stand, while the leading end of a length of stock enters the stand, and is subsequently increased to a greater value. The lower initial stiffness prevents the leading end of a strip from curving sideways, if it has an uneven thickness across its width then it enters the rolls. In one form, Fig. 2, an hydraulic roll gap adjusting cylinder 14 is supplied with fluid from a servo valve 18 in order to provide a high or low stand stiffness. The valve is operated by a controller 15 connected to a switch 26. The switch one of two transmitters 24 and 25 to the controller, the transmitters corresponding respectively to a reduced stiffness characteristic and a normal one. Also connected to the controller are a roll position sensor 22, a strip gauge sensor 23, and a desired gauge value 21. The switch 26 may be operated in one of several ways; by a photo-cell 27 which detects the presence of a hot workpiece, or by a pressure cell 19 and roller 28 which detect when the workpiece has entered the next stand of a tandem mill by the change in tension incurred. Alternatively, load cells 34 detecting changes in the stand loading, a prsssure transducer 17, or current relays sensitve to changes in the current supply to the drive motors of the stand, may operate the switch.

Abstract: 748,608. Internal - combustion operated free-piston rammers. OYER, G. May 8, 1953 [May 8, 1952] No. 12859/53. Classes 7(2) and 7(3) In an internal-combustion operated free piston rammer for driving piles, sheet piling and the like only a part of the volume of the air subjected to the action of the piston is compressed to the pressure corresponding to the point of spontaneous ignition of the mixture of air and fuel, means being provided for propagating the ignition to that part of the volume which is not compressed to such a high pressure. In the rammer shown in Fig. 3, fuel is injected on the upstroke of the piston 11 and drops into a cavity 15. On the downstroke the ram strikes the anvil 12 and the fuel is atomized and ignited owing to the temperature reached. Rich mixture in the course of combustion is blown from the space 16 towards the space 17 and combustion is completed in the latter space. As shown in Fig. 4, passages 19 are obliquely arranged and produce a violent gyratory movement in the space 17. The compression ratio in the space 16 is higher than in the space 17. In Fig. 5, the fuel is injected by means of injectors 22 and ignites on contact with the air. In Figs. 6 and 7 injectors 23 inject during the upward stroke of the piston. Fig. 7 shows the piston at the lower end of its stroke. The temperature of the air is sufficient to produce ignition.
Patent GB-458467-A (GB)
Title: Process for the manufacture of nitro-cellulose
IPC: C08B5/02
Filed: 1936-05-07
Abstract: Cellulose nitrate is obtained by treating cellulosic raw material with a nitrating medium containing chlorine in an amount substantially less than the weight of the cellulose.  There may be added to a normal nitrating acid mixture an amount of hydrochloric acid which is less than the weight of the cellulose material to be treated.  The viscosity characteristics of the cellulose nitrate produced may be varied by adjustment of the proportion of chlorine in the nitrating medium, an increase in the amount of chlorine resulting in a decrease in viscosity of the cellulose nitrate.  Products suitable for making lacquers or plastic masses may be directly obtained.  In an example, bleached pine wood cellulose containing resin impurities are nitrated with a mixture of sulphuric acid, nitric acid, and water, containing an addition of hydrochloric acid. A pure white cellulose nitrate is obtained.  In another example cotton linters are treated with a mixture of sulphuric acid, nitric acid, water and hydrochloric acid.  The process enables pure white cellulose nitrate to be obtained directly from off-white cellulosic raw material.
